Successful treatment of a patient with recurrent ovarian clear cell adenocarcinoma under combination chemotherapy of 5-FU (civ) and low-dose CDDP (i.v.)

Resistance to conventional chemotherapy including CDDP is the most important therapeutic problem in ovarian cancer. The combination chemotherapy of 5-FU (civ) and low-dose CDDP (i.v.) was applied to a patient with recurrent ovarian clear cell adenocarcinoma (stage IIa), which is often more resistant to systemic chemotherapy than other ovarian adenocarcinomas and is a poor prognostic factor. The patient underwent cytoreductive surgery. Then, 5-FU 375 mg/m2/day civ (days 1-5, 8-12, 15-19, 22-26) and CDDP 3.75 mg/m2/day i.v. (days 1-5, 8-12, 15-19, 22-26) were administered. After four courses of this treatment, there is no sign of recurrence. This result indicates that the combination of 5-FU and CDDP is useful in the treatment of recurrent ovarian cancers.
